Specification of Letters Patent.

Patented April 10, 1906.

Application filed ly 8, 1905. Serial No. 268,895.

To all whom it may concern:

Be it known that we, J AMES THOMAS HATH- ERLY and THOMAS HENRY HATHERLY,subjects of the King of Great Britain, and residents of NewIVestminster, in the Province of British Columbia and Dominion ofCanada, have invented a new and Improved Adjuster for Electric-LightCords, of which the following is a full, clear, and exact description.

This invention relates to adjusters for electric-light cords, thepurpose of the invention being to produce a device of this class whichis very simple of construction and which may be readily manipulated inorder to dispose of any quantity of slack in the cord resulting from theparticular position or height desired for the electric light carried bythe cord.

The invention consists in the construction and combinations of parts tobe described more fully hereinafter and definitely set forth in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar reference characters designatesimilar parts in all the views.

Figure 1 is a side elevation of the device, showing a portion ofelectric-light cord and illustrating the manner of passing the cordthrough the adjuster. Fig. 2 is an elevation of the device as viewedfrom the left side of Fig. 1. Fig. 3 is a transverse central sectiontaken on the line 3 3 of Fig. 1. Fig. 4 is a transverse section taken onthe linev 4 4 of Fig. 1, but in an inverted position; and Fig. 5 is adevelo ed view of the body of the device and a fan of the blank fromwhich the device is a apted to be formed.

The body of the device is preferably formed of sheet metal or similarmaterial and is most conveniently formed from a blank 1, such as thatillustrated in Fig. 5. The body of this blank is substantially ofelongated rectangular form, terminating in inclined and reduced necks 2.Beyond these necks laterally-projecting tips or ears 3 are formed. Atsubstantially the central line of the blank 1 is formed alaterally-projecting head 4, having a reduced throat 5.

In forming the body 6 of the adjuster from this blank the edge 7 of theblank opposite the head 4 is rolled upwardly, as indicated in Fig. 3, sothat a rudimentary tubular opening 8 is formed extending from end to endof the device. As will appear, however, from inspection of Figs. 1 and3, the circumferential wall of this tube is not complete at any point,so that a longitudinally-dis osed slot 9 is formed. On account of the 0'set necks 2 at the extremities of the blank this slot 9 becomes slightlyhelical, as indicated at 10 in Figs. 1 and 2. The body of the blank inthe vicinity of the throat 5 is offset inwardly, as indicated in Fig. 3,so that it lies substantially in the plane of the tubular body. To theouter edge 11 of the head 4 we attach a horn 12, which extendslongitudinally of the body and consists of a bent bar, the middle pointwhereof is located at the head 4, the extremities 01 the said horn beingbent outwardly in a curve, as indicated, tapering toward theirextremities and terminating in enlargements, balls, or heads 13. To theouter side of the horn 12 and at the head 4 there is attached a cap orbutton 14, which consists of a circular disk of metal or similarmaterial.

In rolling the blank to form the body of the device in the mannerdescribed above the ears 3 are preferably allowed to retain their flatform at their outer portions, as indicated most clearly in Figs. 1 and4. In this way the openings at the extremities of the tubular body aresomewhat enlarged, so as to facilitate the attachment of a cord 15. Inattaching the cord the same would be twined into the slot 9 from one endof the device. Provision is made for the slack which is to be taken upat the throat 5, and at this point the cord would be wrapped in coils 16thereabout, as indicated in Fig. 1. Beyond this point the cord isreturned to the tubular body and passes out through the lower extremitythereof, as shown. The projecting extremities of the horn 12 affordample means for retaining the coils 16 and facilitate the wrappingthereof about the projecting head 4.

From an inspection of Fig. 2 it will be seen that an opening 17 in tothe helical slot 9 is formed between the ears 3 and a substantiallystraight edge 18. This effect is produced by forming the rear side ofthe ears 3 with a straight longitudinal edge, as indicated in Fig. 5.

The device described is evidently very simple in construction and may bereadily ICC manipulated so as to enable the electric-light cord tosupport an incandescent lamp at any desired height. Having thusdescribed our invention, We claim as new and desire to secure by LettersPatent 1. An electric-light adjuster, consisting of a plate rolled so asto present a tubular body, sald plate having an integral head projectinglaterally from said body, said body being adapted to have anelectric-light cord passed therethrough, said. head being adapted tohave said cord disposed in coils thereabout. 21. An electric-lightadjuster, consisting of a plate rolled so as to present a tubular body,said plate having an integral head projecting laterally from said bodyat substantially the middle point thereof, and a horn attached to saidhead and disposed in a plane substantially parallel With said body, saidbody being adapted to have the electric-light cord passed therethrough,said head being adapted to have the cord wrapped thereabout.

3. A device of the class described consisting of a plate rolled into abody having substantially tubular form, said body having alaterally-projecting head, and a horn carried by said head and extendinglongitudinally of said body, said horn affording means for retaining thecoils of the cord passed about said head.

4. A device of the class described, comprising a substantially tubularbody having a slot in the Wall thereof through which an electric-lightcord may be passed, said body having a laterally-disposed head adaptedto have coils of cord passed thereabout, and a horn attached to saidhead and disposed longitudinally of said body, said horn affording meansfor retaining said coils.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
